Hi Sam,
Thanks again for the continued discussion and for highlighting the nuance between scaling and upgrading.
You’re absolutely right that upgrading is one way to achieve vertical scaling, and that the two terms aren’t strictly interchangeable in general computing. That said, in Azure’s App Service context, “scaling up” refers specifically to changing the pricing tier, and this action directly affects the underlying resources, including CPU, memory, and other capabilities.
As shown in the official documentation, selecting a higher pricing tier not only unlocks features like deployment slots and custom domains, but also increases compute resources: https://learn.microsoft.com/en-us/azure/app-service/manage-scale-up#scale-up-your-pricing-tier
We won’t be changing the term in this question since “scale up” is explicitly used in Azure’s official documentation to describe this action. Keeping terminology aligned with platform standards helps reinforce clarity for learners preparing for certification.
